Best thing: High 2.5K resolution at up to 155 Hz
Honest catch: No built-in speakers
If the screen is mostly for games — a handheld on a hotel desk, a console at a friend’s place or a gaming laptop — this is the one: high resolution, a fast refresh rate and Adaptive-Sync without flagship pricing. It has no speakers, so plan on headphones through the jack or your console, and consoles over HDMI top out at 120 Hz; 155 Hz is for USB-C sources only.
Up to 155 Hz over USB-C and 120 Hz over HDMI make games and scrolling look far smoother than the 60 Hz of most portable screens.
Adaptive-Sync matches the refresh rate to the game’s frame rate, cutting tearing and stutter.
2560 × 1600 on 16 inches is sharper than a 1080p portable, and the taller 16:10 shape shows more of a map, page or timeline.
Mini HDMI with the included cable takes consoles and older laptops; USB-C takes handhelds, phones and laptops with video output.
Power pass-through up to 65 W lets one charger feed both the monitor and your laptop.
A 1/4-inch tripod socket lets you raise it to eye level on a camera tripod (tripod sold separately).

Yes, if its USB-C port outputs video (DisplayPort Alt Mode, Thunderbolt or USB4) — then one cable carries picture and power, and ASUS says USB-C is where the full 155 Hz is available. If not, use mini HDMI for the picture and power the monitor through USB-C from an adapter.
Yes, through the mini HDMI port with the included mini-HDMI-to-HDMI cable; over HDMI the refresh range is 48–120 Hz, and the monitor needs power through USB-C. ASUS also pitches it for handhelds such as the Xbox Ally X and Nintendo Switch 2.
No. Use the earphone jack, or headphones connected to your console, handheld or laptop.
